[0025] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" appearing below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0027] Examples, such as Figures 1-7 As shown, this utility model provides a sliding sealing mechanism and an insulated box using the sliding sealing mechanism, including a guide rail 1. The guide rails 1 are arranged in pairs and can be connected to the inner top of the insulated box by countersunk screws. The top and bottom of the guide rail 1 are both flat. Guide grooves 11 are provided on both sides of the guide rail 1. A moving component 2 is provided on the guide rail 1 to slide with it. The moving component 2 includes a top square tube 21. The top square tube 21 is provided with two mounting ports 22 that correspond one-to-one with the guide rail 1. Two... A clamping assembly 3 is elastically fitted to both sides of the guide rail 1. The clamping assembly 3 includes a clamping block 31. The end of the clamping block 31 contacts and fits with the side of the guide rail 1 and the groove surface of the guide groove 11. A groove-shaped cross plate 32 is provided on the side of the clamping block 31 opposite to the guide rail 1. The cross plate 32 is movably fitted to both sides of the top square tube 21. An inner square tube 33 is provided on the inner side of the cross plate 32 and is movably inserted into the top square tube 21. A spring 34 is provided in the inner square tube 33. A blocking plate 25 is provided inside the top square tube 21 and contacts the spring 34.

[0028] Specifically, in the direction of movement of the moving component 2 along the guide rail 1, the clamping component 3 and the assembly port 22 can form a sliding seal with the three sides of the guide rail 1. In particular, the clamping component 3 can maintain a dynamic sealing clamp with the guide groove 11, which has good sliding sealing performance. If an unbalanced disturbance occurs on both sides of the guide groove 11, the spring 34 provides compression and restoring force to the clamping component 3, so that the moving component 2 and the guide rail 1 have relatively flexible movement ability. When the moving component 2 and the guide rail 1 are stationary, the clamping component 3 can effectively seal both sides of the guide groove 11, and the cross plate 32 can seal the movement margin of the assembly port 22 and the clamping block 31, effectively reducing the cold flow surface of adjacent temperature zones, which is beneficial to improving the control performance of this equipment for different temperature zones.

[0029] To improve the fit between the clamping block 31 and the guide rail 1, the clamping block 31 provided by this utility model has a groove on the side facing the guide rail 1, and a T-shaped sealing gasket 35 is provided in the groove. The sealing gasket 35 contacts and fits with the groove surface of the guide groove 11. The edge of the groove can contact the groove surface of the guide groove 11 to provide rigid support, while the sealing gasket 35 provides soft support and has a certain friction with the groove surface of the guide groove 11. This improves the sealing fit between the clamping block 31 and the guide rail 1 in a static state and prevents the mutual flow of cold air between the two sides of the moving component 2.

[0030] To improve the sensitivity of the clamping block 31 in providing elastic support, the inner square tube 33 provided in this invention has multiple roller grooves at both its top and bottom, with self-rotating cylindrical rollers 36 installed in the roller grooves. The cylindrical rollers 36 provide rolling support for the inner square tube 33 and the top square tube 21, providing guidance while reducing the resistance of the inner square tube 33 during horizontal extension and retraction. This allows for timely balancing of the disturbance generated by the clamping block 31 and the guide rail 1, thereby improving the smoothness of manually pushing the moving component 2 to move linearly along the guide rail 1.

[0031] Furthermore, this utility model provides a key-shaped hole 37 on the span plate 32. The key-shaped hole 37 cooperates with the guide keys 23 provided on both sides of the top square tube 21. The two ends of the key-shaped hole 37 can provide two limiting nodes for the guide keys 23. On the one hand, it assists the spring 34 in providing better elastic support for the clamping assembly 3. On the other hand, it avoids the phenomenon of the span plate 32 jumping up and down, which is conducive to improving the cooperation performance between the clamping assembly 3 and the guide rail 1, and can extend the actual service life of this sliding sealing mechanism to a certain extent. Among them, the guide keys 23 are located in the lower half of the top square tube 21, that is, the vertical height of the span plate 32 is greater than the height of the clamping block 31 and the assembly port 22. This provides a basis for the cooperation between the key-shaped hole 37 and the guide key 23, and is also conducive to the span plate 32 sealing and blocking the area of ​​the assembly port 22.

[0032] To facilitate the connection between the top square tube 21 and plate-like structures in other application scenarios, the top square tube 21 provided by this utility model includes a square tube section 211 and an insert plate section 212. The insert plate section 212 is a downward-opening groove-shaped structure, and multiple screw holes 24 for installing screws are provided on the insert plate section 212. In this way, the partition inside the insulation box can be inserted below the insert plate section 212, and a reliable connection relationship can be established by screws, so that the partition and the sliding sealing mechanism can move synchronously inside the insulation box.

[0033] To facilitate control of the specific position of the moving component 2 on the guide rail 1, this invention provides multiple positioning holes 12 spaced apart along the length of the guide rail 1, and a positioning component 4 that mates with the positioning holes 12 is provided on the top square tube 21. By providing the positioning component 4 to mate with the positioning holes 12 at different positions, the real-time position of the moving component 2 can be controlled.

[0034] Furthermore, the positioning component 4 provided by this utility model includes a guide sleeve and a cross rod 42. The top end of the cross rod 42 passes through the guide sleeve 41, and a plug 43 is provided at the top end of the cross rod 42. A return spring 44 is provided between the plug 43 and the guide sleeve 41. Both ends of the cross rod 42 are provided with bent rods 45, and the top of the bent rods 45 is provided with positioning heads for insertion into positioning holes 12. The bottom of the cross rod 42 is for pulling up and down by hand. The cross rod 42 can move up and down under the action of pulling force. The lowest position of the cross rod 42 is controlled by the return spring 44 and the plug, and the return spring 44 provides automatic return elasticity for the cross rod 42. The positioning heads at both ends of the cross rod 42 can be inserted into the positioning holes 12 to realize the positioning of the moving component 2. The positioning relationship can be released when the positioning heads leave the positioning holes 12, so as to facilitate the adjustment of the front and rear positions of the moving component 2.

[0035] An insulated box employing a sliding sealing mechanism includes the sliding sealing mechanism. Inside the insulated box, a partition 51 connected to a moving component 2 is provided. The partition 51 has double-opening flip doors 52. A cooling fan and an exhaust window are located above the flip doors 52. Each flip door has a handle, and the partition structure between the flip doors 52 has handles 53 for pushing and pulling the partition 51. By connecting the partition 51 to the sliding sealing mechanism, a synchronous movement relationship can be established, and a sliding sealing node can be provided for the partition 51. Simultaneously, the flip doors 52 adopt a heat-insulating plate design, and can be flipped and closed via hinges, improving the sealing and heat insulation effects after closure. Figure 7 As shown, in order to improve the movement of the partition inside the insulated box, the present invention provides a cylindrical support structure on the bottom edge of the box body, and the bottom of the partition 51 is provided with an arc-shaped opening that cooperates with the support structure. Without affecting the sealing performance, the arc-shaped opening can reduce the movement resistance of the partition compared with the right angle fit.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
